Abstract (en)
A process of preparing a color filter array element for use in making a color liquid crystal display device comprising: a) overlaying a dye-receiving element with a dye-donor element, the dye-receiving element comprising a dimensionally-stable temporary support having thereon, in order, a polymeric alignment layer, a transparent conducting layer and a dye-receiving layer; b) imagewise heating the dye-donor element to transfer a dye image in a repeating mosaic pattern to the dye-receiving layer; c) removing the dye-donor element from contact with the dye-receiving element; d) laminating a transparent permanent support to the dye-receiving layer containing the dye image in a repeating mosaic pattern; and e) removing the temporary support to expose one surface of the polymeric alignment layer, thereby forming the color filter array element. <IMAGE> <IMAGE>
